Edit text Pro

Edit the text itself

Double-tap a paragraph or a table cell and type. Fix a date, a name or a price in seconds.

  • Choose the font, size, bold, italic, underline, alignment and color.
  • The old words are removed from the page, not hidden, so they can’t be found or copied later.
  • On a scanned page, the old words are covered with the page’s color.

  • Draw your signature once and reuse it, with the date beside it if you like.
  • Place a picture, such as a stamp or logo, then move or resize it.
